This is the episode page where I summarise each episode without spoiling too much! I hope you enjoy. Episode 1 starts with the introduction of Crystal, a high-esteemed and determined young teenager. She has a normal life complete with a boyfriend by her side name Robert and a best friend named Angel. However, her life changes completely when a mysterious and malevolent young girl named Madelyne from the deep space begins to cast a spell on her classmates by putting heart gems on the special love bands Angel's class is selling at school. Soon the classmates start hitting each other and Angel figures out something is terribly wrong with the love bands. Angel goes to the inventory room and Madelyne appears before Angel. Angel panics and is knocked uncounscious by the falling boxes int the inventory room. Crystal senses Angel in trouble but just as she begins to run, Crystal is transported to a mysterious place, there she sees a blue orb and touches it. This sends her back to school, but now she wears a mysterious armor. Crystal goes to the inventory room and comfronts Madelyne, who has created a being called Heart Soldier. Madelyne used the negative energy of the teens with the love bands to create this soldier. Madelyne commands the soldier to attack Crystal and they fight. Crystal winds in the end and Madelyne's spell is broken. Madelyne shouts at Crystal and vanishes. Crystal's armor disappears and helps Angel in the inventory room. Angel thinks it was just a dream. Crystal doesn't realize it is her first battle of many to come.

Episode 2 begins with Crystal along with Angel, Robert, Eve, and Greg attend an opera for a school assignment. Robert falls asleep during the play and Angel tells Crystal to accompany Angel to the bathroom. Greg too wants to go and Eve accompanies them as well leaving Robert alone. The people watch the opera as they go to the restrooms. Meanwhile, Madelyne has put a heart gem on the singers costume earlier and when she activated it the singer was transformed into Madelyne's knight which she calls it Dread Knight. The knight puts the audience into a time-freeze spell and notices Robert wakes up. Madelyne commands the knight to get him. When Crystal and the other come back they are shocked at what they see. Greg faints and Eve tries to fight it. Crystal goes off and transforms into the Mystic Warrior of the Crystal and fights Dread Knight who has knocked Angel unconscious. Eve then too is transported to a mysterious place with a blue orb. She touches it and she is transported back to the opera wearing a silver armor known as the Nobleman armor. They battle Dread Knight fiercely and win. Madelyne sneers and disappears. Eve and Crystal help place Greg and Angel in their seats to think they were dreaming. When they did so their armors disappear and the Dread Knight turns into a singer once more. The spell broken brings the audience back again and they enjoy the opera.

Episode 7 is the final showdown with Madelyne. At the start of the episode, Madelyne is threatened by Diane and is warned if she fails to defeat the Mystic Warriors again she will be dealt with. In desperation, Madelyne appears before the high school where Crystal and Eve attends to lure the Mystic Warriors to a showdown at the city plaza at midnight. Crystal and Eve decide to go to end Madelyne's reign of terror once and for all. When they arrive at the town plaza at midnight, Madelyne shows up and has a few tricks up her sleeve. She makes the Mystic Warriors fight each other using her charm powers, but they overcome her charm and attack her. Madelyne attacks them several times. Each time with more power. Finally Crystal and Eve combine their strentgh to defeat Madelyne once and for all. Or so it seems.

She tells Diane she will take over Madelyne's tasks and find the energy source. However, Polaris is curious of the Mystic Warriors' fighting skills and decides to test them out on combat. She creates a rain of hail to warm up on her elemental powers and in the process lures the Mystic Warriors. Polaris challenges them to a duel and the Mystic Warriors accept. They fight long and hard, but surprisingly Polaris WINS! However, just as she is about to finish them off, she sees the Mystic Warriors can increase their fighting potential and admrires their honorable combat. She decides she will spare them and wait till the Mystic Warriors gain enough fighting status to the ranks of Polaris. She will send 'soldiers' made completely out of magic to raise their power levels. When they are finally at Polaris fighting level...then she will finish them off. Polaris believes honorable combat is the purest form of fighting.
